PATENT OFFICE ASSIGNOR 'ro MIL ER. MANUFACTUBING COMPANY, OF BAINBRIDGE, GEORGIA METAL-BELT GONVEYER Application filed December This invention relatesto improvements in metal belts particularly adapted for endless belt conveyer devices in bottle washing machines or other suitable apparatus.

An object of this invention is to provide improved belt links and conveying belt surface consisting of plates of a suitable type for carrying the article to be conveyed. The links and plates to be formed of separate metals rigidly connected together by means of casting or any other suitable process.

A further object of this invention is to provide links and plates for a flat top belt conveyer, the plates being of brass or other metal and cast or otherwise joined to the links in such a manner as to form a unit of two metals.

Other objects of this invention will appear in the following detailed description and as disclosed in the single sheet of drawings herewith made a part of the application.

In the drawing,

Fig. 1 illustrates a plan view of a metal beltconveyer, having suitable links and flat conveying surface plates.

, Fig. 2 represents a plan view of a belt link and plate of a sn nny modified type over the plates and links disclosedin Fig. 1.

Fig. 3 illustrates an end clevational View of Fig. 2.

Fig. 4 represents a sectional elevatlonal view of Fig. 3 taken at 4-4.

Fig. 5 is a sectional view of the link and plate disclosed in Fig. 1.

Fig. 6 illustrates a side elevatlonal v1ew of alink and plate in modified form of Fig. 1.

Fig. 7 is an end sectional view of Fig. 6 taken on line 7-7.

Numeral 1 designates a conveylng plate preferably having a flat surface and made of brass or other metal, it being understood that the conveying surface may be flat or otherwise without efiecting the merits of this invention, the plate 1 being adapted to be cast or otherwise securely fastened to the link portion 2, the link portion being composed of a metal having durable qualities such as malleable iron or the like, the two elements 1 and 2 thereby forming a link and plate suit- 50 able for a metal belt conveyer used in bottle 1, 1925. .Serial No. 72,482.

washing machines or other similar types of apparatus. -The link 2 has a head 3 from which extend furcations 4, the upper furcation having the horizontal crescent shaped bearing plate 1 secured thereon at its outer end. A vertical opening 5 is formed in the head 3 and extends therethrough. Another opening 6 is formed in the bearer plated and extends through the furcations which are in alignment directly under each other and the bearer plate 1. By having the link union thus formed, a plurality of linksmay be connectedtogether, as shown in Figure 5, by means of pivot elements 7. The head 3 fits between the adjacent furcations 4 and, is secured in place by pivot means 7 which extends through the opening 6 in the bearer plate 1 on through the top furcation, and in turn through the head'placed beneath'the same and through the opening in the lower furcation. Thus a continuous conveyerchain is formed.

The crescent type conveyer is the most efficient, it being capable of flexing right or left of its straight course without breaking or gaping between its plates.

In this invention it is to be understood that the link 2 may be a casting as commonly used in conveyer and transmission belts, wh1le the holding plate 1 may be of any suitable metal. Thls invention, therefore, provides a chain having the ordinary durable, and malleable features common to certain metals maintaining their desired unity with a plate or carrier constructed of a separate or more suitable metal for carrying purposes.

Figs; 1 and 5 of the drawings discloses a flat toplbeltconveyer, consisting preferably of malleable links, with flat tops of brass or other material, cast to the link,thereby form'- v ng the link and plate into a unit of two metals 1n such a manner that the chain portion retains its malleable feature and at the same time maintains its desired unity withthe plate or carrier made of a more suitable material or metal. In forming the conveyer section disclosed in Figs. 1 and 5, link 2 may be a malleable element commonly used in conveyer and transmission belts, while the plate 1 may be preferably of brass, the link being cast first and set into the plate mould and then formed or cast inseparately together, thereby providing the combination of an approximate crescent shaped brass plate and U shaped pintle type malleable iron link and the plates cast inseparately to the links in a position transversely to a pintle joint on one side of the links.

A modified form of the invention is shown in Figs. 2, 3, and 4:, it differs from the above description of Figs. 1 and .5 principally in design of conveying plates, and in the fact that it is only capable of running in a straight line, and therefore is of very much'simpler construction.

The modified form of this invention as disclosed in Figs. 6 and 7 provides a cup-link and results in increased strength to the link and uniformity to the cup, .facilitates production and reduces cost.

As in the construction shown in Figs. 1 and 5, the link portion is a malleable casting or other suitable metal common to conveyers and transmission chains or belts, hook or pintle type. The cup portion may be of cast iron which does not warp as malleable iron does.

The forming of a malleable link and grey iron cup is accomplished preferably by first casting the malleable link then placing it into the mould for the grey iron or other suitable metal cup whereby the cup is cast inseparately to the link thus making the link and cup practically one casting, and at the same time, possessing the feature of having the best adapted metal in the link and another metal best suited in the cup.

What I claim is:

A conveyer comprising a plurality of onepiece links each having a head and furcations extending therefrom, one furcation of each link having a horizontal crescent shaped bearing plate secured thereto at the outer end thereof, there being vertical openings in each of said plates and in the furcations and head of each link, said openings being designed to receive pivot elements whereby the links may be pivotally connected. 7
